Performances by R.E.M., Willie Nelson and Patti Smith are other musical additions, but the recordings don’t have to have a beat to make the collection. A tape of sounds from World War II will also be archived.

In order to be added to the registry, recordings must be at least 10 years old and have cultural, historical or aesthetic significance. If you want to recommend some Hanson for next year's list, you can nominate it by clicking here.
